That doesn't even remotely resemble a best fit curve. They've drawn the line straight-through an outlier. And look how steep it is at the right hand side. They're asking us to believe that the marginal impact of increasing corporate income tax rates above the Norwegian level is not only negative, but massively negative in a way that none of the non-Norway data bears out.
